HUB AND AXLE.

SPECIFICATION forming part of Letters Patent N0. 623,784, dated April 25, 1899.

Application filed November 21, 1898. Serial No. 697,093. (No model.)

To all whom it may concern:

Be it known that l, ALBERT HODGSON, a citizen of the United States, residing at T- ronto, in the county of Woodson and State of Kansas, have invented certain new and useful Improvements in Hubs and Relative Devices; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to vehicle hubs, axleboxes, and axles; and the purposes of the same are to provide a convenient mode of applying vehicle-wheels, prevent wear on the engaged parts, obviate to a material degree the loss of the lubricant by working or running out from the hub, and consequently require less ma.- terial of this character to be used and not in such frequency of application as in ordinary devices, form a practical sand-band and dirtproof bearing, and preserve a neat external appearance and dispense with irregular surface projections, as Well as cheapen the cost of manufacture.

. The invention consists of the construction and arrangement of parts more fully hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a part of a vehicle wheel and axle, showing the improvement applied thereto. Fig. 2 isa central longitudinal vertical section of the improved device as shown by Fig. 1 on a larger scale.

Referring to the drawings, wherein similar numerals are utilized to indicate corresponding parts in both views, the numeral 1 designates a hub composed of a wooden core 2,.

having oppositely-disposed thimbles 3 and 4 thereon, provided with outer flanges 5 at their inner ends, spaced apart from each other for reception and securement of the spokes. The core 2 has a central outwardlytapered bore 6, having diametrically-disposed recesses 7 at the inner enlarged part thereof, and. in said bore a tapered elongated box 8 is removably mounted- The outer reduced end 9 of the box is closed and exteriorly screw-threaded and near the inner enlarged end has opposite splines 10, which engage the recesses 7 and prevent the box from turning in the core 2. In rear of the position of the splines 10 the box has an exteriorly-screw-threaded collar 11, secured to or integral therewith,and said collar is reamed or otherwise cut out interiorly to form an opening 12 of larger diameter than the bore 6. A shoulder 13 is thus formed at the outer termination of the opening 12 by the inner end of the box. WVhen the box 8 is in place in the core, the collar 11 abuts against the inner end of the same, and a cylindrical bur 14 is run on the outer reduced screw-threaded end 9 and bears against the outer end of said core.

The end of the axle 15 is reduced to form a spindle 16, and at the inner part of the latter screw-threads 17 are located and slightly in advance of the point where the reduction of the axle starts. The part of the axle imme: diately in rear of the screw-threads 17 being of greaterdiameter than the said threads provides a shoulder 18 for a purpose which will be presently described. In forming the screw-threads 17 the spindle is not weakened, because said threads have a greater diametrical extent than the spindle, and the bases of said threads are flush with the adjacent circumferential surface of the spindle. On the spindle 16 a cap-bur 19 is loosely placed and has an outer open end with interior screwthreads and a rear substantially closed end 20 with a central opening 21 therein. The opening 21 is larger in diameter than the threads 17, but less than .the shoulder 18 on the axle, and consequently said bur 19 is limited in its inward movement and free to pass over said threads 17. A leather or analogous washer 22 is fitted against the inner surface of the end 20 of the bur and surrounds and is movable over the axle with the latter and prevents the entrance of dust or grit and also the exit of the lubricant. After the bur 19 is in place, as set forth, an interiorly-threaded sleeve or cylindrical nut 23 is slipped over the spindle 16 and caused to adjustably engage the threads 17, and against the said .sleeve a washer 24, of suitable material, is also fitted. After the parts specified are mounted on the spindle the latter is prepared for insertion in the box 8, which has a predetermined length of bore and just large enough diametrically to receive said spindle without friction. When the spindle is located in its box, the sleeve 23 enters the collar 11 and abuts against the shoulder 13, and a firm connection and tight joint is established by drawing the bur 19 up to and screwing it on'the collar 13. The outer end of the bur 19 snugly bears against the rear end of the thimble 4:, and the exterior shape of the said thimble and bur is such that they virtually become continuous and without break or irregularity. The sleeve 23 is intended to be slightly moved or shifted on the spindle to compensate fora possible wear on the end thereof next the bur. The washer 2i occupies an interposed position between the shoulder 13 and sleeve 23 when the latter is brought up to said shoulder, and thus the lubricant is effectually held in the box and prevented from oozing out to any great degree.

By reason of the peculiar construction of the device the usual frequent application of a lubricant is avoided, because the loss of the same by running out of the hub is materially overcome. The parts are also so fitted that no noise will issue therefrom, and in the event of wear on the outer end of the spindle the reduction in length may be quickly compensated for by adjusting the sleeve engaging the threads on the inner part of the spindle. Strength and durability are also encouraged by the specified construction, and owing to the comparatively few number of parts they are easily articulated and convenience in assemblage also results.

Having thus described the invention, what is claimed as new is- In combination with an axle having aspindle of uniform diameter throughout its length shouldered at its inner end, and having the inner portion threaded, and a sleeve adj ustably mounted upon the threaded portion of the spindle, a tapered box mounted upon the spindle and having its inner end recessed to receive the adjustable sleeve and exteriorly threaded, and having its outer end closed and externally threaded, a core slipped upon the box and interlocking therewith to prevent relative turning, a nut applied to the outer threaded end of the box and bearing against the outer terminal of the core, thimbles mounted upon the end portions of the core and having outer flanges at their inner ends, the outer thimble overlapping the joint between the nut and the end of the core and the inner thimble terminating flush at its inner end with the inner terminal of said core, and a cap-bur making screw-thread connection with the inner end of the box and recessed to receive and bear against the aforesaid adjustable sleeve and having its rim abutting against the inner extremities of the core and inner thimble and coming flush with the outer side of the latter, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT I'IODGSON.
